Using proportions, it is found that the infusion rate is of 150 ml/hr.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 50 ml are administered over 20 minutes. How much is administered over one hour = 60 minutes? The <em>rule of three</em> is:
50 ml - 20 min
x ml - 60 min
Applying cross multiplication:
x = 50(60)/20
x = 50(3)
x = 150.
The infusion rate is of 150 ml/hr.

Answer:
x = y = z = 94
Step-by-step explanation:
• All the sides of a rhombus are congruent
then
x = y = z = 94
First simplify the stuff in the (), 4^6 is equal to 4,096. Next let’s take care of the 2, if a number is outside of the () then you have to multiply whatever is inside the () by that number in this case multiply 4,096 by 2. You should get 8,192. Find out what number goes in 8,192 enough times for example, the number 2.
Final answer: 2^13
You have the base which is 2 and the exponent which is 13.
Answer:
125.6 cm²
Step-by-step explanation:
Area of the shaded region = area of larger circle - area of the smaller circle
Area of the smaller circle = πr²
π = 3.14, r = 3 cm
Area of smaller circle = 3.14*3² = 3.14*9 = 28.26 cm²
Area of larger circle = πr²
π = 3.14, r = 7
Area of larger circle = 3.14*7² = 3.14*49 = 153.86 cm²
Area of the shaded region = 153.86 - 28.26 = 125.6 cm²
